Conversion Formula
nPa = PPa × 1.000000000e+24
About Petapascals
A petapascal (PPa) = 10¹⁵ Pa - pressures found in stellar interiors. The Sun's centre is ~25 PPa, sustained by radiation pressure from nuclear fusion balanced against gravity. White dwarf stars: ~10⁴ PPa (electron degeneracy). Neutron stars: ~10⁹-10¹⁰ PPa, where nuclear structure fails and neutrons drip from nuclei at ~4 × 10⁸ PPa (the neutron drip line). The hadron-quark phase transition in the densest neutron star cores is estimated at 10¹⁰-10¹² PPa. No laboratory experiment can approach petapascal pressures. 1 PPa = 10¹⁵ Pa.
About Nanopascals
A nanopascal (nPa) is 10⁻⁹ Pa - the pressure scale of deep interplanetary space. LIGO and Virgo gravitational wave detectors must isolate mirror displacement signals against noise floors in the nanopascal regime. Low Earth orbit residual atmosphere is ~100 µPa; deep interplanetary space is ~1-10 nPa depending on solar wind activity. Thermospheric gas layers above 200 km altitude fall into the nPa-µPa range. Casimir force calculations and quantum vacuum fluctuation modelling also operate at nanopascal scales. 1 nPa = 10⁻⁹ Pa.
